In this paper we investigate, determine and classify the critical configurations for solving structure and motion problems for 1D retina vision. We give a complete categorization of all ambiguous configurations for a 1D (calibrated or uncalibrated) perspective camera irrespective of the number of points and views. It is well-known that the calibrated and uncalibrated case are linked through the ci

The thermal elimination reaction that appears in some polycarbonates has been studied by density functional theory (DFT) and ab initio methods of different levels. This work has been focused in the elimination process of ethyl formate, as a good model of this kind of reaction. Different minima and the transition state have been found to characterize the thermal elimination reaction, and the activa

Popular Abstract in Swedish Det förgångna är framtiden är en socialantropologisk studie av ett politiskt skeende som pågått under de senaste 20 åren och som handlar om hur ursprungsfolket kanaka maoli i Hawai´i fått rätt till självbestämmande och andra särskilda rättigheter. Kanaka maoli har använt en diskursiv strategi som handlat om att de en gång i tiden varit ursprungligt suveräna och att dennThe sovereignty- and self-determination movements of indigenous peoples are a salient factor on the political agenda in many western world countries. Indigenous peoples in Hawai´i and elsewhere have become increasingly politicised in hope of changing their relationship with the states within which they are located. The discourse of indigenous peoples turn around the concept ”First Nations” whose c

Popular Abstract in Swedish Denna undersökning inventerar beståndet av beteckningar för EGENDOM I ALLMÄNHET och för MOBIL och IMMOBIL EGENDOM i de regionala medeltida nordiska lagarna (dvs. de danska och svenska landskapslagarna, de norska lagtingslagarna samt den isländska Grágás). Materialet analyseras språkgeografiskt med avsikten att skapa en relativ termkronologi. En grovanalys visar attfé/fæThis study investigates the stock of words for PROPERTY IN GENERAL with the subcategories MOVABLE and IMMOVABLE PROPERTY in the regional medieval Scandinavian laws and makes a linguistic-geographical analysis of these words with the aim of establishing a relative term chronology. A crude analysis shows that fé/fæ for PROPERTY IN GENERAL and land for IMMOVABLE PROPERTY were the oldest terms. A seri

In this paper we study how a system with a time-periodic impulse response may be expanded into a sum of modulated time-invariant systems. This allows us to define a linear frequency-response operator for periodic systems, called the harmonic transfer function (HTF). Similar frequency-response operators have been derived before for sampled-data systems and periodic finite-dimensional state-space sy

BACKGROUND AND OBJECTIVES: During the past 10 years several DNA-typing methods have been developed to complement routine serological typing for determination of polymorphisms in the ABO, RH, KEL, JK and FY blood group genes. However, the molecular basis of blood groups can differ widely between ethnic groups. The purpose of this study was to evaluate selected DNA-based methods for phenotype predic

Popular Abstract in Swedish Läkaren har en viktig roll när det gäller att tillförsäkra människor vård på lika villkor. Mötet mellan läkaren och patienten präglas alltid av maktobalans. Studier världen över visar att invandrarpatienter är en sårbar grupp eftersom invandrare generellt har sämre tillgång till vård, sämre förutsättningar för hälsa och sämre hälsotillstånd jämfört med majoritetspopulatPhysician and patient do not meet as equals in the consultation. It is the responsibility of the physician to actively work for better communication in order to provide equitable health care for all individuals. Immigrant patients are a vulnerable group, shown in studies all over the world to have less access to care, fewer opportunities for health, and poorer health compared to majority populatio

Adsorption of formic acid (HCOOH) on ZnO() surfaces has been investigated by means of quantum-chemical ab initio periodic Hartree–Fock calculations. One ‘bridging' structure, characterized by a formate anion symmetrically bonded via its two oxygens to two surface Zn atoms and the acidic proton bound to a surface oxygen, and two ‘unidentate' structures, characterized by one Znsurf–Oads bond and the

Bark lesions on beech are mostly caused by frost damage and/or insect and fungal infections. Liming, treatment with wood ash and N-fertilization were hypothesised to affect this type of damage. The frost sensitivity was measured as an index of injury, calculated from electrolytic leakage of bark samples. Samples were taken from the same trees in August and November at five sites. Two sites had bee

Phosphodiesterase 3B (PDE3B) is an important component of insulin and cAMP-dependent signalling pathways. In order to study phosphorylation of PDE3B, we have used an adenoviral system to express recombinant flag-tagged PDE3B in primary rat adipocytes and H4IIE hepatoma cells. Phosphorylation of PDE3B after treatment of cells with insulin, cAMP-increasing agents, or the phosphatase inhibitor, calyc

A Holocene lake sediment record is presented from Lake N14 situated on Angissoq island 15 km off the main coast of southern Greenland. The palaeoclimatic development has been interpreted on the basis of flux and percentage content of biogenic silica, clastic material, organic material and sulphur as well as sedimentation rate, moss content and magnetic susceptibility. A total of 43 radiocarbon dat

Background: Oxidative stress is implicated in the pathogenesis of several complications of prematurity. The glutathione cycle is one of the most important intracellular antioxidant systems. The synthesis of glutathione may not be adequate in preterm neonates because of the low levels of cysteine available. The aim of this study was to evaluate cysteine and glutathione metabolism during the first w

The mitochondrial permeability transition (mPT) is a potential pathogenic mechanism in neurodegeneration. Varying sensitivity to calcium-induced mPT has been demonstrated for regions within the CNS possibly correlating with vulnerability following insults. The spinal cord is selectively vulnerable in e.g. amyotrophic lateral sclerosis and increased mPT sensitivity of mitochondria derived from the

Data from field experiments carried out in the swash zone on two Pacific beaches in Japan were analyzed to determine net sediment transport rates and the resulting foreshore response. The experiments involved artificial modification of the foreshore slope with a bulldozer, either making the slope steeper or milder, after which a wide range of measurements were performed as the slope evolved back t

The silicon vacancy in its neutral charge state (V-Si) has been unambiguously identified in 4H- and 6H-SiC. This was achieved by observation of ligand hyperfine interaction with the four carbon atoms in the nearest-neighbor shell and the twelve silicon atoms in the next-nearest-neighbor shell surrounding the vacancy. The complete hyperfine tensors have been determined for the V-Si(0) center residi
